AUXILIARY HOLDER FOR LA-I VIZ? GLOBES, SHADES, 8w.

Specification of Letters Patent. Patented Feb. 21, 1911.

Application filed J'une 1910. Serial No. 568,374.

To all whom it may concern:

Be it known that I, MAX Hnnsnovrrz, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Auxiliary Holders forLamp Globes, Shades, &c., of which the following is a specification.

The subject of the present invention is an auxiliary holder which isadapted to be removably attached to a globe, shade, chimney, or thelike, of a lamp, so that they are separably held together, and theauxiliary A serious objection to most globe-holders now in use .is thatthey contact with the globe at a number-"of distant points andconsequently, by reason of the superior conduc-. tivity of metal ascompared with a r, the

globe is subjected to a more intense heat at these points of contactthan at other parts,

with the result that the expansion and contraction of the globe isunequal and it cracks. Furthermore the pressure of the straddle arms orclamping screws produce pressure upon the globe which is more or lessunequal and this increases thetendency to breakage.

The object of the present invention is to provide an auxiliaryglobe-holder adapted to be interposed between the globe and the mainglobe-holder and Whichv when so inter-, posed will obviate theabove-named ob cc-- tions to globe-holders of many of the kinds now inuse. To this end the improved auxiliary. globe-holder is of suchconstruction that it may be readily attached to globes of many of thewell-known kinds and whenso attached may be engaged by-globe-holders ofmany of the well-known kinds; it will contact with the globe throughoutthe entire extent of their adjacent surfaces so that the transmission ofheat to the globe will be uniform throughout; it will clamp the globeeither firmly so as to prevent it from-shak ing about, or loosely so asto permit a free air space between them for carrying oft the heat; itmay be used in either upright or inverted position: with eitherelectricity or gas; and with either an open or an incan 'descent burner.

In short, the invention relates to the mixiliary globe-holder adapted tobe interposedbetween the globe and the main globe-holder, regardless oftheir construction excepting that they must be adapted to each other.

To this end the invention consists in the features of-novelty that arehereinafter described with reference to the accompanying drawing, whichis made a part of this specif cation, and in which:

Figure 1 1s a vertical central section of an inverted, incandescent gaslamp, having an auxiliary globe-holder embodying the invention. Fig. 2is a similar view of an up right lamp. Fig. 3 is a horizontal section,on a smaller scale, of the auxiliary globeholder. I I

The improved auxiliary globe-holder consists of an inner ring-A and anouter ring B, both ofwhich are preferably spun of suitable metal. Theinner ring has a lateral shoulder, a, extending outwardly, which"preferably is in the form of a lateral flange of somewhat largerdiameter than the burner opening of the globe, C, so that it willoverlap the margin. of the globearoundthe burner opening and engage theinner face thereof. In allinstances the maximum diameter of the lateralshoulder which engages the inner face of the globeis'greater than theburner opening. If the globe has also an opening .of greater diameterthan the shoulder. of the ring located opposite the burner opening, I itmay be put in place through this larger opening, but if the globe isentirely closed, save for the burner opening, or has 'no opening largeenoughto permit the ring and its shoulder to pass through (assuming theshoulder and opening to be circular) it may be inserted through theburner opening by making the shoulder or opening non-circular. This ispreferably done by cutting away the shoulder on one or more chords ofits circumference as shown at a. The ring A may then be inserted throughthe burner opening edge- Wise and put in place. and the clamping ring l3secured to it. also, has a lateral shoulder 6, extending outwardly,which is preferably in the form of The clamping ring,-

. ter than the a lateral fian e of somewhat larger diamedourner. openingof the globe,

so that it"will -overlap the margin'of the "globearound'the burneropening and en'- jgage the outer face thereof, but'in all cases thisflange may; be fof" uniform diameter throughout. TheririgS, vA andB,are-relatively adjustable, preferably by means of engaging screw threadsformed on them, so .10

that the fiangesa andb, maybe adjusted r to any desired distance'ap'art,accordingly'as it is desired to firmly clamp the globe be-' tween them,or. allow .a slight play between them, the latter-being preferable forthe reason that it'- allows free circulation of air for carrying off theheat. In either event shoulders are positively held so that. the globeWill'be positively supportedbythe thenlowermost shoulder and preventedfrom g slipping-down, over the burner when used in either arr-invertedposition, as shown. in

Fig." 1,-which "shows an inverted incandes-' cent'igas burner,'D, or anupright position a as shown .in' Fig. 2, which shows. an uprightincandescent gas burner,

. The outer end-of theinner ring A is spun so as toprovidean outwardlypresented groove a adapted to securev the ends of the set screws,- F, asis shown in Fig.1; -or. the p30.

Q main globe-holder such as shown in Fig.2,

reflexed ends of the spring arms,.G,' of a to-which, main globe-holderthe improved 'j-globe-holde'r is auxiliary. In either event an incidentor result .of the groove is the v the screws or fingers of the mainglobeholder project, whereby the auxiliary globeholder is firmlysupported whichever side is uppermost. i

What I claim as new and desire to secure by Letters Patent is: Y i

An auxiliaryglob'e-holder havin inthe other, said rings havingengaging screw threads wherebythey' are adjustably secured together, theinner ring having at one of its ends a lateral shoulder adapted toengage the inner surface of-the-globe and at the other ceive theglobe-holding devices 0 the main globe-holder, and the outer ring havinga surface of the globe.
